Description

Technical Field

[0001] The utility model belongs to the technical field of smelting furnaces, and in particular relates to a rotary aluminum chip smelting furnace. Background Art

[0002] Aluminum is a recyclable metal. Recycling scrap aluminum can not only reduce the mining of alumina ore and the manufacture of electrolytic aluminum, thereby reducing the consumption of natural resources and reducing environmental damage to nature, but also improve resource utilization and reduce production costs.

[0003] Scrap aluminum recycling mainly uses a smelting furnace. During operation, aluminum chips are put into the cylinder of the smelting furnace for melting. The cylinder in the smelting furnace is often fixed. When the aluminum chips are put into the cylinder, the aluminum chips will gather at the bottom of the cylinder under the action of gravity, which greatly reduces the melting efficiency of the aluminum chips and affects production. Secondly, the heating wire for heating the cylinder in the existing smelting furnace is set close to the cylinder, which causes adhesion between the heating wire and the cylinder, thereby causing a short circuit or leakage, posing a safety hazard.

[0007] Furthermore, the inner cylinder includes a crucible and a stainless steel layer wrapped around the outside of the crucible.

[0008] Furthermore, the fiber layer is attached to the inner surface of the outer cylinder, and a gap is reserved between the thermal insulation layer and the electric heating wire heater.

[0009] Furthermore, a distance is maintained between the electric heating wire heater and the inner cylinder.
